Dual-Patented Aesthetic Thermal Armor.
Woqin Aero-Stone is a revolutionary thermal cladding system designed for modern facade engineering. By utilizing our proprietary bonding technology—protected by both National Invention and Utility Model patents (App. No. CN202610254198.9 & CN202620256735.9)—we seamlessly bond a 3mm Modified Clay Material (MCM / Flexible Stone) veneer directly to our high-performance Silica Aerogel blanket. The result is an ultra-lightweight, flexible, and fireproof solution that drastically reduces structural deadweight.
Total Thickness: Flexible customization from 6mm to 23mm (3mm MCM Stone + Aerogel Core).
Weight: Ultra-lightweight at approx. 4-5 kg/m² (eliminates heavy steel anchoring).
Finish: Natural Flexible Stone (Travertine, Slate, Rammed Earth, etc.).
Fire Rating: Class A (A2-s1, d0) - Non-combustible.
Technology: Dual-Patented Composite Structure.
Description
Product Overview
Designed for architects and facade engineers, Woqin Aero-Stone solves the critical challenges of high-rise cladding and retrofits. Traditional stone facades require expensive, heavy mechanical anchoring systems (steel sub-frames) and bulky insulation that eats into cavity space. Aero-Stone delivers the authentic texture and visual impact of natural stone in a flexible, insulated panel that can be directly bonded to the substrate.
Key Engineering Benefits
Drastic Weight Reduction (No Sub-frames): Weighing just ~4 kg/m², Aero-Stone is up to 90% lighter than traditional stone slabs. It can be applied directly over existing renders, masonry, or insulation boards using polymer adhesives, entirely eliminating the need for expensive steel support brackets.
Architectural Flexibility (Curved Surfaces): Unlike rigid cladding, the MCM facing and aerogel core are highly flexible. Aero-Stone effortlessly wraps around structural columns, curved walls, and tight architectural radii without cracking.
Patented Composite Technology: Our proprietary bonding process (Utility Model Patented) ensures the flexible stone and aerogel act as a monolithic layer. It withstands extreme thermal cycling and wind loads without delaminating.
Uncompromising Fire & Weather Safety: The entire system is Class A Non-combustible. With a low water absorption rate (8.13%) and high UV stability, it is engineered to withstand severe rain, frost, and sun exposure on exterior building envelopes.
Ultra-Slim Thermal Performance: Starting at an unprecedented 6mm, the aerogel core (0.020 W/m·K) provides maximum thermal resistance, making it the ultimate choice for upgrading the energy efficiency of older buildings where exterior space is limited.

Installation Guidance
Direct Bonding (Paste Application): Aero-Stone eliminates the need for mechanical fasteners. It is installed using a high-quality flexible polymer adhesive (Class C2TE or S1/S2) directly onto sound concrete, masonry, or existing render. This dramatically speeds up site application.
Curved Installations: For curved facades or cylindrical columns, the material naturally bends to accommodate the radius. For extremely tight radii, a gentle application of a heat gun can increase the pliability of the MCM facing.
Jointing & Grouting: Panels can be installed with a standard grout gap (using exterior-grade flexible pointing mortar) for a traditional masonry look, or butt-jointed for a sleek, contemporary monolithic finish.
Cutting: No heavy wet-saws required. It can be easily cut on-site using a standard utility knife or angle grinder, significantly reducing harmful silica dust on site.
Frequently Asked Questions (FAQ)
Q: What is the advantage of your patented composite structure?
A: Our technology is strictly protected by dual national patents (Invention Patent App. No. CN202610254198.9 and Utility Model App. No. CN202620256735.9). Traditional glued composites often fail, warp, or delaminate under high-rise wind loads and thermal expansion. Our patented preparation method ensures a permanent, weather-proof monolithic bond between the MCM stone and the aerogel blanket.
Q: Can you custom-match specific colors or brick/stone textures for my project?
A: Absolutely. Custom color and texture matching is one of our core capabilities as a direct manufacturer. You can simply mail us a physical sample of your original brick slip or stone veneer. Our lab will custom-engineer the MCM facing to replicate the exact color, texture, and tactile feel with >90% visual accuracy. This service is particularly ideal for heritage building retrofits or projects with strict municipal zoning guidelines.
Q: Can Aero-Stone be used for high-rise building retrofits?
A: Absolutely. Because it weighs starting from just ~6 kg/m² and is Class A fireproof, it is the premier choice for retrofitting high-rise facades. It adds virtually no deadweight to the old structure compared to traditional 50kg/m² stone slabs, and complies with strict modern fire safety regulations.
Q: Does it actually look and feel like real stone?
A: Yes. The MCM facing is manufactured using natural stone powder and soil, baked under low heat. It perfectly replicates the organic texture, color variation, and tactile feel of natural stone, slate, or rammed earth.
Q: How do I specify this for my architectural project?
A: We work directly with facade engineers and architects globally. Please contact our technical team to request a Commercial Sample Box (including various stone textures and aerogel thicknesses) and DWG detail files for your CAD designs.
